Elevated Operating Ambient TemperatureIf installed
in a closed or multi-unit rack assembly, the operating
ambient temperature of the rack environment may be
greater than room ambient. Therefore, consideration
should be given to installing the equipment in an
environment compatible with the manufacturer's
maximum rated ambient temperature (Tmra).
Reduced Air FlowInstallation of the equipment in a
rack should be such that the amount of air flow
required for safe operation of the equipment is not
compromised.

Mechanical LoadingMounting of the equipment in
the rack should be such that a hazardous condition is
not achieved due to uneven mechanical loading.
Circuit Overloading Consideration should be given
to the connection of the equipment to the supply circuit
and the effect that overloading of circuits might have
on over current protection and supply wiring.
Appropriate consideration of equipment nameplate
ratings should be used when addressing this concern.
Reliable EarthingReliable earthing of rack-mounted
equipment should be maintained. Particular attention
should be given to supply connections other than direct
connections to the branch circuit (e.g., use of power
strips).

Introduction
This chapter describes the features of the Switch and some
background information about Ethernet/Fast Ethernet
switching technology.
Fast Ethernet Technology
The growing importance of local area networks (LANs) and
the increasing complexity of desktop computing
applications are fueling the need for high performance
networks. A number of high-speed LAN technologies have
been proposed to provide greater bandwidth and improve
client/server response times. Among them, 100BASE-T
(Fast Ethernet) provides a non-disruptive, smooth evolution
from the current 10BASE-T technology. The non-disruptive
and smooth evolution nature, and the dominating potential
market base, virtually guarantee cost effective and high
performance Fast Ethernet solutions in the years to come.
100Mbps Fast Ethernet is a new standard specified by the
IEEE 802.3 LAN committee. It is an extension of the 10Mbps
Ethernet standard with the ability to transmit and receive
data at 100Mbps, while maintaining the CSMA/CD Ethernet
protocol. Since the 100Mbps Fast Ethernet is compatible
with all other 10Mbps Ethernet environments, it provides a
straightforward upgrade and takes advantage of the
existing investment in hardware, software, and personnel
training.
Switching Technology
Another approach to pushing beyond the limits of Ethernet
technology is the development of switching technology. A
AirLink+

switch bridge Ethernet packets at the MAC address level of
the Ethernet protocol transmitting among connected
Ethernet or Fast Ethernet LAN segments.
Switching is a cost-effective way of increasing the total
network capacity available to users on a local area network.
A switch increases capacity and decreases network loading
by dividing a local area network into different segments,
which don't compete with each other for network
transmission capacity.
The switch acts as a high-speed selective bridge between the
individual segments. The switch, without interfering with
any other segments, automatically forwards traffic that
needs to go from one segment to another. This multiplies
the total network capacity while maintaining the same
network cabling and adapter cards.
For Fast Ethernet networks, a switch is an effective way of
eliminating problems of chaining hubs beyond the “tworepeater limit.” A switch can split parts of the network into
different collision domains, making it possible to expand
your Fast Ethernet network beyond the 205-meter network
diameter limit for 100BASE-TX networks. Switches
supporting both traditional 10Mbps Ethernet and 100Mbps
Fast Ethernet are also ideal for bridging between the
existing 10Mbps networks and the new 100Mbps networks.
Switching LAN technology is a marked improvement over
the previous generation of network bridges, which were
characterized by higher latencies. Routers have also been
used to segment local area networks, but the cost of a
router, the setup and maintenance required make routers
relatively impractical. Today switches are an ideal solution
to most kinds of local area network congestion problems.

Features
The Switch is designed for easy installation and high
performance in an environment where traffic on the
network and the number of user increase continuously.
The Switch, with its rack size, is designed for middle- to
large-sized workgroups. The Switch provides immediate
access to a rapidly growing network through a wide range
of user-reliable functions.
The Switch is ideal for deployment with multiple high-speed
servers for shared bandwidth 10Mbps or 100Mbps
workgroups. With the highest bandwidth 200Mbps
(100Mbps full-duplex mode), any port can provide
workstations with a congestion-free data pipe for
simultaneous access to the server.
The Switch is expandable by cascading two or more
switches together. Since all ports support 200 Mbps, the
Switch can be cascaded from any port and to any number of
switches.
The Switch is ideal for sites planning to upgrade to Fast
Ethernet in the future. Ethernet workgroups can connect to
the Switch now, and change adapters and hubs anytime
later without needing to change the Switch or reconfigure
the network.
The Switch combine dynamic memory allocation with storeand-forward switching to ensure that the buffer is
effectively allocated for each port, while controlling the data
flow between the transmit and receive nodes to guarantee
against all possible packet loss.

If any item is found missing or damaged, please contact
your local reseller for replacement.
Installation
The site where you install the Switch stack may affect its
performance. Use the following guidelines when installing
the switch:
•
•
•
•
Install the Switch in a cool and dry place. See
specifications for the acceptable temperature and
humidity operating ranges.
Install the Switch in a site free from strong
electromagnetic field generators (such as motors),
vibration, dust, and direct exposure to sunlight.
Leave at least 10 cm of space at the front and rear of the
hub for ventilation.
Install the Switch on a sturdy, level surface that can
support its weight, or in an EIA standard-size
equipment rack. For information on rack installation,
see the next section, Rack Mounting.
When installing the Switch on a level surface, attach the
rubber feet to the bottom of each device. The rubber feet
cushion the hub and protect the hub case from scratching.
Rack Mounting
The switch can be mounted in an EIA standard-size, 19-inch
rack, which can be placed in a wiring closet with other
equipment. Attach the mounting brackets at the switch's
front panel (one on each side), and secure them with the

provided screws (see Figure 1).

Then, use screws provided with the equipment rack to
mount each switch in the rack (see Figure 2).
